Back in the days, when most roads were a far cry from what we know today the Ride Control was standard equipment and an indispensable device for the rider to react to road conditions. By turning the hand wheel you can adjust the spring action and the bounce is taken out of the front wheel on rough roads for safe riding at high speeds. As a rule of thumb you decrease friction the better the road gets and the lower the speed is, at which you ride. This detailed reproduction comes complete, ready to bolt on. A must for any restauration.
